Optical Properties Of In-Based Fluoride Glasses Doped With Er3+

Fluoroindate glasses containing 1,2,3,4 mol% of ErF3 were prepared in a dry box under argon atmosphere. Absorption and emission spectra of these glasses at room temperature were obtained. The Judd-Ofelt parameters for 4f-4f transitions of Er3+ ions as well as transitions probabilities, branching ratios, radiative lifetimes, and peak cross sections for stimulated emission of each band were determined. The concentration effect on the intensities is analysed. The optical properties of the fluoroindate glasses doped with Er3+ ions are compared with those of other glasses described in the literature.
